I have some wild violet and strawberry in my lawn. Last week, I sprayed some 8.8% Triclopyr at a rate of 1 oz/gallon with surfactant. It was stump killer and didn't have mixing instructions for lawn weeds, so I'm not 100% sure I mixed the right amount. I looked at similar products and did some math. It doesn't seem to have done much. Anyone know what the proper mixing amount should be?
